Question

Which one is more acidic and why? CH3COOH or CL3CCOOH?

Answer 1

Check which of the two conjugate bases is more stable.

Answer 2

And the stronger acid would have the weaker conjugate base right?

Answer 3

Answer 4

i would ask myself: what is the key difference between the bonding structures? then i would look up the factors that stabilize the conjugate base, like vincent-lyon said.

Answer 5

it works on inductive effect chlorine being more electronegative try to pull the negative charge of O- of acetate ions so it can liberate the H+ very easily :)
hence Cl3COOH is more acidic :)

Answer 6

Correct. The conjugate base \(CCl_3COO^-\) has its negative charge stabilised by inductive effect.
Hence it is more stable than \(CH_3COO^-\), hence \(CCl_3COOH\) is a stronger acid than \(CH_3COOH\) .

Answer 7

Yup thats what i thought too :) @chmvijay

Answer 8

@moni2529 thank you for that :)

Answer 9

Yup @ anoop27
